The 22-580 is the first Planer I’ve ever owner, or used so my experience is limited. I am just a hobbyist woodworker, but this is what I have to say about it: Bought the 22-580 in February 2006 and have not had a complaint with it except the dust hood is an extra 30 bucks; consider the hood a mandatory purchase. I have not had a bit of problem with the dust collection as other reviewers, and have filled 2 Delta DC bags so far. Note that this is a finish planer and perhaps not intended to make many passes with deeps cuts. At installation, the tables were spot on, as was the knife and the outfeed roller height.Blade life has been a common complaint but having run several hundred BF of hard ash, and recently some quilted maple with the same blades, I haven’t had that problem. The blades are double sided and reversible too. The cutting depth can be changed in very small increments (1/128” division on the height adjustment), and that has been mighty handy when dimensioning figured maple. Another really excellent feature is the “Blade Zero Indicator”. It is used to find the top of your board and works something like a mousetrap mechinism: raise the cutter head above the thkness of the board and “set” the spring loaded indicator. Place the fist ½” of the board into the planer, under the indicator. Now lower the cutter head slowly. When the cutter head is at the same height as the indicator, the indicator snaps, indicating the cutter head is at the same height as the board. You can now set the height gauge to zero. Its very accurate. There is a “head lock” mechanism that is supposed to reduce snipe. I have only seen snipe on one heavy ash timber, so I started using the lock and had ZERO snipe. With smaller boards, I don’t use the head lock and snipe is almost non- existent. The 22-580 has a very convenient “stop” mechanism you can preset to get the same thickness on multiple pieces- once you reach your finish thkness, the stop prevents you from lowering the cutter any further- very elegant design. I’ve found the stop to be more than useful when dimensioning multiple pieces.All in all, based on my limited experience with planers, I have to say this is an excellent machine with features that serve a real purpose and work with precision. I hope I can still say that after I change the blades.
